IMPROVEMENT IN IEANNINGMILLS.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom it may concern Beit known that I, HENRY BRUGeEMAmot Peters-- burg, in the county of Pike, and State of Indianzuhave invented a new and useful Improvement in Fan-Mills; and I do hereby declare that the following is a full, clear, and exact description thereof, 'which will enable those skilled in the art to make and use the same, reference being had to the accompanying dla-wings, formingpart of' this specification, in which-,-

Figure l is a vertical longitudinal section of my improved machine. l

Figure 2 is an end view ofthe same.

Similar letters of reference'indicate corresponding part-s..

My invention has for its object to improve the con struction of fan-mills, so as to adapt them to the various purposes for which such a machine is required by a farmer, such as separating and cleaning grain, removing smut, Ste.; and

1t consists in the construction and combination ot" various parts, as hereinafter more fully described.

A=is the frame of the machine.

B is the case.

C is the fan-shaft, which is pivoted to the frame A, and is operated in the ordinary manner.

D are the fans, which are made in parts, as shown in tig. 1, so that in cleaning small grains, which do not require so much wind ,as thel larger and heavier grains, parts ot' the fans may be removed, to adjust the wind as may be required.

E is the shoe, the inner end of which is suspended from the frame A, by means of an eye-bolt, F.

The other end of the shoe E is suspended from the frame A by the adjustable irons G, the lower ends of which are connected with the sides ot' the shoe E, and the upper ends of which are connected to the frame A, by bolts or pins passing through one or the other ofthe holes in the irons G, and entering holes in the said frame A, so that the position of the shoe E may be adjusted as required for the particular work to be dene..

H is the separating-box, which is stationarily attached to or formed in'the inner part of the shoe E', immediately beneath the first groove in the said shoe.

In the bottom of the box H is formed a hole, through which the particles or tine seeds, that may enter the said 'box E, pass into-the hose or iiexible spout I, by which they are conducted to the iioor, or into some suitable receptacle, without mixing with the grain upon the other sieves or screens.

By this means, and by using coarse or line screens, according to the kind of grain to be operated upon', the operator may separate any desired grain.

The groove ofthe shoe E, may be'extended back, so that any screen or sieve now iu use may be used iu the mill, by pushing them back, and making them even with the box H.

The box H also serves to concentrate the wind and direct it more fully upon the grain, thus giving a greater cleaning power to the mill.

' The middle screen, when placed inthe groove ez, vwill detain the grainmomentarily, allowing light substances, such as chan, smut, &c., to be blown ont.

-For heavier substances, the said screen should be placed inthe groove c or e.

The lower screen is adjusted in position by means of the set-screws J, upon the ends of which the said screen rest-s.

The plate K, which may be made of tin, wood, or other suitable material, and which is represented as being interposed between the said lower screen and the screws J, is provided with an upwardly-projecting flange, rising above the rear ends of said screen, which, when the rear end of the said screen is raised, prevents the grain or seed from being blow over.

L is a rubber, onothcr gum-elastic roller, the journals of which revolve in eye-bolts or other adjustable bearings, attached to Ithe frame M, or to the top of the Inill, and to which motion is given from the fan-l shaft C, by bands passing around the said fan-shaft, and around the shaft of the roller L, and the length or tautue'ss of which bands is regulated by the adjustable pulleys N, over which the said bands pass.

O is a sheet-metal concave or trough, adjustably suspended from the frame VM, by the boltsand nuts P, so that the said concave may be moved nearer to or farther from the roller L, according to the size ot' the grain to be cleaned of smut.

As the grain passes through the concave O,` the smut is crushed from the kernels of' grain, without injuring said kernels, and while the grain escapes over the edge ot' the concave O, the ,smut-passes through the holes formed in the said concave, and falls into the box H, from which it passes out of the mill.

The smut falls into the box H, just in the rear of the guard-plate Q, made ot' tin, or other suitablev material, and placed upon the shoe E, as shown in iig. l.

It should be observed that the smut-roller L should not be usedl until the light smut has all been blown from the grain.

I claim as new, Patenty 1. The smut-roller L, constructed as described, and perforated adjustable concave O, in combination witlrthe shoe E and frame A of a fan-mill, substantially as herein shown and described, and for the purpose set forth.

2. Adjusting the lowerscr'cen of the shoe E by and desire to secure by Letters .means of the set-screws J, substantially as hereinshown and described.

- 3. The combination of t-he flanged plate K with the adjusting-screws J, and lower screen of the shoe E, of the fan-mill, substantially as herein shown and described, and for the purpose set fort-h.

HENRY BRUGGEMAN.
